ATO 나노 입자들로 구성된 적외선 차단 박막이 솔-젤 법에 의해 성공적으로 제조되었다. 코팅액은 유무기 하이브리드 바인더와 콜로이드 ATO 용액으로 합성되었고 ATO 박막은 슬라이드 유리기판에 5~40 mm/s의 인상속도로 코팅되었다. 인상속도가 5 mm/s에서 40 mm/s로 증가함에 따라 코팅막의 두께 또한 $1.05{\mu}m$에서 $4.25{\mu}m$로 증가하였다. 그리고 파장 780 nm에서 2500 nm에서의 적외선 차단율은 49.5 %에서 66.7 %로 증가하였다. 또한 $80^{\circ}C$에서 건조된 ATO 박막의 연필경도 값은 5H를 나타내었고 tetraethylorthosilicate와 methyltrimethoxysilane을 합성한 하이브리드 바인더의 영향으로 테이프테스트 후 코팅막은 벗겨지지 않았다. 서로 다른 인상속도에 의해 제조된 박막의 표면구조, 광학적 특성 그리고 박막두께는 FE-SEM, UV-Vis-NIR 분광기 그리고 Dektak에 의해 측정되었다.

Sb doped SnO2(ATO: Antinomy doped Tin Oxide) thin films were prepared by a DC magnetron spttuering method using an oxide target and the electrical characteristics of ATO films were investigated. The experimen-tal conditions are as follows :Ar flow rate ; 0~100 sccm deposition tempera-ture ; 250~40$0^{\circ}C$ DC sputter powder ; 150~550W and sputteing pressure ; 2~7 mTorr, The thickness of depositied ATO films were 600$\AA$~1100 $\AA$ ranges. The resistivity of ATO films was decreased due to the increase of the crystallinity of ATO films with deposition temperature. The decrease of carrier concentration of films with the increase of oxygen flow rate and working pressure is responsible for the increase of resistivity. Increasing of sputtering power raised the resistivity of films by decreasing the carrier mobility.

Volatile flavor compounds of Chamaecyparis obtuse essential oil were extracted by simultaneous steam distillation extraction (SDE) and supercritical fluid extraction (SFE) and analyzed by GC-MS. A total of 48 and 50 components were identified in essential oil by SDE and SFE, respectively. Monoterpenes, oxygenated monoterpenes, sesquiterpenes, oxygenated sesquiterpenes, and diterpenes in essential oil by SDE were 37.24, 10.9, 9.61, 0.22, and 0.22%, respectively. In the case of SFE, they were 19.1, 23.3, 22.66, 1.31, and 10.57%, respectively. Antioxidant activities were increased with the increase of essential oil up to $80{\mu}L/mL$, irrespective of extraction method. Especially, when the essential oil concentration extracted by SDE was increased from 20 to $80{\mu}L/mL$, the antioxidant activity was increased from 10.5 to 55.1%. However, over $80{\mu}L/mL$ of essential oil, an equilibrium state was maintained. In the case of essential oil extracted by SFE, it was decreased compared to that of SDE. For the improvement of atopic dermatitis, various cosmetics such as an ato-cide soap, ato-cide spray, and ato-cide lotion containing essential oil extracted by SFE were tested. About over 90% was useful for the improvement of atopic dermatitis after 4 weeks of clinical trial targeting 40 female adults. These results demonstrate that ato-cide soap, ato-cide spray, and ato-cide lotion containing essential oil extracted by SFE could be used in functional cosmetics.

본 연구에서는 RF Magnetron Sputtering 법으로 94:6 wt%의 비율로 Sb가 첨가된 $SnO_2$ 타겟을 사용하여 실온에서 ATO(Antimony doped Tin Oxide) 박막을 증착하고, 열처리가 ATO 박막의 구조적, 전기적, 광학적 특성에 미치는 효과를 연구하고자 하였다. ATO 박막의 두께는 약 200 nm로 증착하였으며, 실험 조건으로는 Ar 유량을 100 seem, 진공도는 1, 5, 10 mTorr로 변화시켰으며 스퍼터링 파워는 100, 150, 200, 250 W로 조절하였다. 증착되어진 박막은 vacuum 상태에서 300, $600^{\circ}C$의 온도에서 열처리를 수행하였으며 결과적으로 스퍼터링 파워가 증가함에 따라 비저항이 감소하였고, 250 W의 파워와 10 mTorr의 공정압력 조건에서 $600^{\circ}C$로 열처리한 ATO 박막은 $5{\times}10^{-3}{\Omega}-cm$의 저항률과 85.3%의 높은 투과도를 가지는 우수한 투명 전도막을 얻을 수 있었다.

본 연구의 목적은 공개 소프트웨어를 활용하여 지역 축제기록을 보존 활용할 수 있는 전자기록관리시스템을 구축하고, 사용한 공개 소프트웨어를 비교하여 축제 기록에 적합한 공개 소프트웨어를 평가하는 것이다. 본 연구의 적용 대상 축제로 춘향제를 선정하였으며, 현재 춘향제 기록관리의 문제점을 제기하여 그 중 축제기록을 보존할 시스템이 없다는 점을 제시하였다. 이후, 기록관리용 공개 소프트웨어인 AtoM(Access to Memory)와 OMEKA를 활용하여 축제기록관리시스템을 구현하였다. 구축된 각각의 시스템을 지역 축제기록의 특성에 따라 비교한 결과, AtoM 기반 축제기록관리시스템이 지역 축제기록의 보존 활용에 더욱 적합한 것으로 나타났다.

본 연구는 민간영역의 중요 기록물을 보호하기 위한 취지로 운영되고 있는 '기록사랑마을'을 대상으로 기록물 관리방안을 제안하기 위해 연구되었다. 2008년부터 매년 지정되고 있는 기록사랑마을이 소장하고 있는 기록물은 2014년 기준 3,000여 점에 달하지만, 기록물 현황 파악이 쉽지 않고, 기록정보에 대한 접근성이 떨어져 이들의 관리와 활용이 어렵다는 문제점을 안고 있다. 이에 본 연구에서는 기록사랑마을 기록물의 관리를 위한 방안으로 앞선 연구에서 제시된 관계자 의견 가운데 하나인 '기록물의 전산화'를 실현하고자 하였다. 이에 기록사랑마을이 직면하고 있는 현실적인 문제로 거론된 '인력과 비용 문제', '시스템 구축의 부담감'을 고려하여, 웹 기반 기록관리용 공개 소프트웨어로 주목받고 있는 AtoM(Access to Memory)을 활용한 기록관리 시스템을 구현하였다.

Objectives : The aim of this study is to investigate anti-atopic dermatitis effect using ato-tang.Methods : Ato-tang was external treatment to NC/Nga mice for 4 weeks, where atopic dermatitis was induced by DNCB at 1% and 0.4% for 3 weeks. Atopic dermatitis index score was measured using eye observation and picture evaluation. The histopathological change of dorsal skin was observed by hematoxylin and eosin (H&E) staining. Cytokines including IL-4, IL-5 and IL-13 were measured by Luminex or reverse transcriptase polymerase chain reaction (RT-PCR) analysis and immunoglobulin E (IgE) was measured by ELISA reader.Results : The dorsal skin of Ato-tang group showed decrease in erythema, pruritus, dry skin, edema, excoriation, erosion and lichenification level through naked eye observations. Immunoglobulin cell infiltration and the thickness of epidermis were significantly decreased in the dorsal skin compared to control. Production of Th2 cytokines (IL-4, IL-5, IL-13) and IgE level in serum were all significantly decreased, in comparison with control. In addition, mRNA expression level of Th2 cytokines (IL-4, IL-5, IL-13) in spleen was decreased, in comparison with control.Conclusion : The results indicated that external treatment of ato was improved skin barrier function in the symptoms of atopic dermatitis disease. Also, atopic dermatitis factors where cytokine as well as immunoglobulin E in serum and mRNA expression were decreased, respectively, in comparison with control. Therefore, we suggest that ato could be effectively used as a external therapeutic drug based on atopic dermatitis factors.

Sb doped SnO2(ATO:Antinomy doped Tin Oxide) thin films were prepared by a DC magnetron spttuering method using oxide target and the deposition characteristics were investigated. The experimental conditions are as follows :Ar flow rate : 100 sccm oxygen flow rates ; 0-100 sccm deposition temperature ; 250 -40$0^{\circ}C$ DC sputter powder ; 150~550 W and sputtering pressure ; ; 2~7 mTorr. Deposition rate greatly depends not on the deposition temperature but on the reaction pressure oxygen flow rate and sputter power,. when the sputter powder is low ATO thin films with (110) preferred orientation are deposited. And when the sputter power is high (110) prefered orientation appeares with decreasing of oxygen flow rate and increasing of suputte-ring pressure.

Antimony (6 wt%) doped tin oxide (ATO) films to improve conductivity were deposited on 7059 coming glass by RF magnetron sputtering method for application to transparent electrodes. The ATO film was deposited at a working pressure of 5 mTorr and RF power of 175 W. We investigated the effects of the post-annealing temperature on structural, electrical and optical properties of the ATO films. The films were annealed at temperatures ranging from $300^{\circ}C$ to $600^{\circ}C$ in step of $100^{\circ}C$ using RTA equipment in vacuum ambient. X-ray diffraction (XRD) measurements showed the ATO films to be crystallized with a strong (101) preferred orientation as the annealing temperature increased. Electrical resistivity decreased significantly with annealing temperatures up to $600^{\circ}C$. ATO film annealed at temperature of $600^{\circ}C$ showed the lowest resistivity of $5.6\times10^{-3}\Omega$-cm. Optical transmittance increased significantly with annealing temperatures up to $600^{\circ}C$. The highest transmittance was 90.8 % in the visible range from 400 to 800 nm.
